I've just reached 180 miles on my new ebike (Bosch mid-drive) and cleaned and lubed my chain and cassette for the first time. I've never done this before. I noticed the teeth on the sprockets showing wear, is this type and amount of wear to be expected after 180 miles?
Not really advanced but - cassette wear after first 180 miles?

Looks fine. I usually get maybe 8000 miles on a cassette but it depends on so much. my first bosch bike I had 14k on the original cassette. on our bosch powered tandem the 13t cog would skip around 2000 miles.

180 miles is too soon to see any extensive wear, but one huge tip is to never shift under load. The mid drive puts a lot more pressure on the drive train than a regular bike, so make sure you let the pedal pressure off before shifting. So far I have almost 7000kms on my original cassette/chain on a Giant/Yamaha mid drive.

this is one thing that gets me on my second gen bosch the spin stops instantly when you stop pedaling the 4 gen it goes a tiny bit when you let up so shifting is clunkier and I see more wear on cassettes.

I see a little bit of wear on one tooth of cog four at the end of the shift ramp, but that's normal as the cog is pressed to create the ramp and it isn't always perfect. Are you having shifting issues? What are you doing for chain maintenance?
No shifting issues, no noise, I just wanted to do this for the first time so I know what to expect. The mess was a little larger than I thought
For chain maintenance, I purchased a chain scrubber, I used purple degreaser (1:1 dilution) and a few brushes for the cassette and derailleur. Rinse 3x with clear water, wait to dry, and finally apply drip-style wax w/tungsten disulfide on each of my 107rollers individually (might've lost count - somewhere near 107).spokewrench

Until 2 years ago, I'd always ridden with hub gears or no gears. When I finally got a derailleur bike, downshifts while climbing were horribly violent. At 2500 miles I found that the chain pitch was still slightly under 0.5", like new, and I saw no wear on the rails or the cassette. I guess I'd learned to make shifts a little gentler with a few milliseconds of anticipation. Also, when I want motor assistance on a climb, the power from my hub motor doesn't go through the chain.
